How many moles are in 1.204 x 1024 formula units of magnesium nitrate?
A mole is 6.023 x (ten to the 23rd power) formula units. (Avogadro's number).
Thus you get your answer by dividing your number by Avogadro's number.
As you have written your number, the answer would be 2.047 x (10 to the minus 21).
However, as the wikianswers font won't let us do superscripts, I think you probably have 1.204 x (10 to the twenty fourth power), and that you are expected to use the approximation 6.02 x (ten to the 23rd power) for Avogadro, which gives a much simpler answer of 20.
Since the pH scale ranges from 0 to 14, a change in one pH unit signifies a tenfold modification in activity. In this case, coffee has a pH of 5, meaning that when compared to the pH of 10 in milk of magnesia, coffee is 100,000 (10 x 10 x 10 x 10 x 10) times more acidic than milk of magnesia.
Is citrate of magnesia safe during pregnancy?
Is citrate of magnesia safe to take during 1st trimester of pregnancy?
Does the body produce magnesium?
No. Magnesium is an element. No chemical or biological process can synthesize elements. We get magnesium from food.
Why does magnesium have no overall charge?
Because for every Mg2+ ion there are two Cl- ions and so the charges balance each other out.
No they are organic. However some vegetables will contain traces of magnesium.
What are indrustial home uses of Magnesium?
magnesium generally are used in plants to make chlrophill. it is also used in the body for hair formations and nails formations.
What happens when magnesium reacts with fluorine?
Under ordinary conditions magnesium burns in fluorine. To see a very brief video search YouTube.com for fluorine reacts with different elements.
What do a mole of magnesium (Mg) and a mole of iron (Fe) have in common?
the answer is there number of atoms
According to the chemist I spoke to at Flinn supply company, a magnesium turning is a small, thin, curled piece of magnesium, like you would get if you were shaving small strips of wood off of a bigger piece.
When 4.00g of magnesium burns the theoretical yield of magnesium oxide is?
2 Mg (s) + O2 (g) → 2 MgO (s)
4.00mg x 1 mol Mg/24.305 x 2 mol MgO/2 mol Mg x 40.305g MgO/1 mol MgO=
=6.63g
4.00g- Given
24.305g- Atomic Mass of Magnesium
40.305g- Atomic Mass of Magnesium Oxide
How are the atoms in Magnesium -24 and Magnesium -26 are similar?
Magnesium is a chemical element with the symbol Mgand atomic number 12. That means the neutral atoms of Magnesium have 12 positively charged protons in their nucleus and 12 negatively charged electrons "orbiting" this nucleus. All atoms of magnesium have this structure.
However accompanying (stabilizing) the protons in the nucleus there are a number of electrically neutral neutrons and this is where atoms of magnesium can vary, there can be 12, 13 or 14 of these neutrons. making Magnesium isotopes (all of which are stable ie not radioactive).
24Mg comprising 78.99% of all the MG on Earth.
25Mg comprising 10.00% of all the MG on Earth.
26Mg comprising 11.01% of all the MG on Earth.
Thus all the atoms of Magnesium are chemically and electrically similar but they have different weights/masses.
What do you need to do 12 hours before a blood test?
Talk to your doctor if you have any questions regarding what you need to do 12 hours before a blood test; especially if they are screening thyroid levels in addition to a metabolic scan. If this is the case, some doctors will want you to fast and take your medication(s) as directed. Typically, if you are only having thyroid levels checked you probably won't be asked to fast. You will want to take your medication as directed, though.
Does magnesium react with aluminium sulphate?
No.Mg is less reactive than aluminum,therefore mg solution will not react with aluminum metal.
Can milk of magnesia be used when a fleet enema has been used?
Yes, milk of magnesia can be used after a Fleet enema, but it's generally advisable to wait a few hours to allow the enema to take effect. Both products are laxatives, but they work in different ways. If you're considering using them together or have specific health concerns, it's best to consult a healthcare professional for personalized advice.
